Letters Patent No. 101,066, dated March 22, 1870.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that 1, WILLIAM Wnsrnnicn, of the city of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Device for Holding Burners to Lamps while the lamps are being filled; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making a part of this specification, in which- Figure 1 repi'esentsa perspective view of my spring or clamp, and

Figure 2 represents it as applied to a lamp.

Like letters refer to the same parts in both figures.

The nature of my invention consists in the construction of a spring or clamp, having its lower points a turned outward, so as to engage the screw-threads on one side of a lamp-collar andthe lamp-wick on the opposite side, and thereby hold the lamp-burner in the position in which it is placed, and also hold the wick on the side of the collar, and give a free opening through the collar for filling the lamp.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

A represents an ordinary lamp.

B, the usual-collar;

O, a lamp-burner; and

E, the wick.

All of these parts are made and operated in any of the known forms or methods.

The clamp D is made 'of spring wire, and in the form shown is crossed; but this form is not especially necessary, as it may be made open, regularly curved, with v stifi arms, and helical springs, or hinged and strained with a screw, and in a variety of other forms.

It operates by holding the wick against the collar with suflicient pressure to prevent the wick from slipping, and is applied as shown tothe inside of the collar, or the spring may be reversed and one arm of the clamp applied to the wick as'shown, and the other arm to the outside of the collar B, immediately opposite to the inside arm; but I prefer the form shown, for the reason that it can he hung onto the spout of the oiloan, and therefore not so liable to be lost or misplaced.

The application of a spring or clamp in this manner also holds the wick against the collar so as to keep the wick out of the way while the oil is being poured, and alsoorercomes the difficulty of disposing of the burner when it is separated from the lamp for the purpose of filling, or for other purposes.

The points a are turned sn'fliciently to insure a hold upon the wick and against the collar.

Having thus fully described my device,

What I claim as new, and desireto secure by Letters Patent, is as follows:

As a new article of manufacture, the device for holding lamp-wicks against the collar, constructed and operating substantially as specified.

' WILLIAM WESTLAKE.
